Michael Werle commented on AVRO-2079:
-------------------------------------
The conventional wisdom of using a pre-sized array to prevent throwing out the
original one is wrong for modern VMs. See the following for exhaustive
performance testing:

> Add ability to use Java 8 date/time types instead of Joda time.
> ---------------------------------------------------------------
>
> Key: AVRO-2079
> URL: https://issues.apache.org/jira/browse/AVRO-2079
> Project: Avro
> Issue Type: Improvement
> Components: java, logical types
> Affects Versions: 1.8.2
> Reporter: Auke van Leeuwen
> Priority: Major
> Labels: patch-available
>
> Currently, for the date/time related logical types, we are generating Joda
> date/time objects. Since we've moved to Java-8 (AVRO-2043) it seems logical
> to also provide the possibility to generate {{java.time.*}} date/time objects
> instead of the Joda time variants.
> I propose to make this is a switch in {{SpecificCompiler.java}} which will
> default to Joda (I think), but can be set to generate the Java 8 versions.
> (I'm currently trying to run through the code to see if I can make it work.)
